Use this filter to customise the content for new columns added to the PDF list view table. This action should be used in conjunction with the gfpdf_pdf_list_columns filter, which actually adds the new column to the table.

The $id in the action name refers to the column ID you set in the gfpdf_pdf_list_columns filter (the array key).

The following snippet shows you how to customise the output of new columns. In this case we added a new column with the stats ID using the gfpdf_pdf_list_columns filter.

add_action( 'gfpdf_pdf_list_column_stats', function( $settings ) {
/**
* Display the current stats which are being stored in the options table.
*
* In retrospect, stats should be stored with the Gravity PDF settings directly,
* but this example shows you how you can manipulate the column output.
*
* Don't forget to change the prefix_ to something unique to your application
*/
echo get_option( 'prefix_gfpdf_stats_' . $settings['id'], 0 );
} );
